Main Methods:

• Literature review of microemulsion applications in drug delivery.
• Analysis of various administration routes including oral, dermal, parenteral, and nasal.
• Investigation of novel applications such as oral solid dosage forms, microreactors, and blood substitutes.

Main Results:

• Microemulsions are effective drug carriers for multiple routes: oral, dermal, transdermal, ocular, vaginal, rectal, buccal, periodontal, parenteral, and nasal.
• Their properties facilitate enhanced drug delivery and bioavailability.
• Potential new applications in solid dosage forms, microreactors, and as blood substitutes are identified.

Conclusions:

• Microemulsions represent a versatile and advantageous drug delivery system.
• Their application spectrum is expanding into novel areas, promising further innovation in pharmaceutical and biomedical fields.
